Embodiment 4

[0051] Embodiment 4 of the present invention provides a mobility management entity MME, the MME includes:

[0052] a receiving unit, configured to receive an ETWS message;

[0053] A setting unit, configured to set an information change flag when the received ETWS message is different from the ETWS message stored by the MME itself;

[0054] A sending unit, configured to send the ETWS message received by the receiving unit and the information change flag set by the setting unit.

[0055] The MME may also include a saving unit, configured to save the received ETWS message and / or the information change identifier.

[0056] Embodiment 5 of the present invention provides a user equipment UE, where the UE includes:

[0057] The execution unit is configured to read the area identifier carried in the system message of the adjacent cell B to which the handover or reselection is performed, and the area identifier is used to indicate the area to which the cell belongs;

[0058] A read...

Abstract

The embodiment of the invention provides a method, a device, and a system for sending and receiving messages. The method for sending messages includes: handing over or reselecting a User Equipment (UE) from a cell A to a neighboring cell B; reading, by the UE, an area identifier carried by a system message of the neighboring cell B, wherein the area identifier indicates an area that covers the cell B; and reading, by the UE, an Earthquake and Tsunami Warning System (ETWS) message carried in the system message if the area identifier is different from the area identifier stored by the UE. Through the embodiment, the UE does not need to reacquire the ETWS messages in the system messages of different cells in the same area, thus saving power.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a message sending and receiving method, device and system. Background technique [0002] Long Term Evolution (LTE) is a next-generation mobile broadband network standard formulated by the 3rd Generation Partnership Project (3GPP) standardization organization. It has high spectrum utilization and transmission speed. Lower transmission delay and other advantages. [0003] By carrying the earthquake and tsunami warning system (Earthquake and Tsunami Warning System, ETWS) message in the LTE system message sent to the user equipment (User Equipment, UE), the LTE system can promptly notify the user of the tsunami warning indication when an earthquake or tsunami occurs, Post-disaster rescue and other related information. [0004] ETWS messages are classified into Primary Notification (PN) and Secondary Notification (SN). The PN carries less content, which is mainly used for ...
